Uniform design experiment on treatment of oil-contaminated soil using microwave radiation
微波修复原油污染土壤的均匀设计实验

The influence of microwave energy,carbon content and water content on removal of crude oil in oil-contaminated soil was researched by uniform design method when the contaminated soil was processed in the microwave field,and the corresponding experimental formula was fitted by MATLAB programming.The results indicate that the removal rate of oil increases with microwave energy linearly at the range of research,rising from 0% to 92.3% with microwave energy changing from 0 to 288 kJ,when carbon content is 4% and water content is 6%.Removal rate of oil increases with carbon content linearly at the range of research,rising from 12.3% to 92.3% with carbon content changing from 0% to 4%,when microwave energy is 288 kJ and water content is 6%.Removal rate of oil changes with water content which is fitted parabolic relation,and the best water content in oil-contaminated soil using the microwave thermal remediation is 6.6%.Research results provide a valuable reference for optimizing the technology of treating oil-contaminated soil using microwave.
